产品概述: Fluke 28II Ex 本安型真有效值数字万用表
福禄克工业用 DMM 具备所有的测量功能。
无论您位于 ATEX 1 区、2 区、21 区还是 22 区的内部或外部，该工具可为您提供所需的全部测试和故障排除功能。无需针对不同区域携带不同的仪表，也无需担心携带非防爆等级的工具穿过防爆要求的区域。
4-1/2 数字模式实现准确测量 (20,000 字)
真有效值交流电压和电流可准确测量非线性信号
可测量高达 1000V 和 10A 的交流和直流电压和电流（注意 Ex 区域要求减少测量）
低通滤波器确保对变速驱动器 (VSD) 准确测量电压和频率
高达 200 kHz 的频率和占空比可帮助您诊断 VSD 和开关电源
电阻、连通性和二极管测试
电机启动电容或元件的电容量范围为 10,000 μF
高电阻或漏电测试电导测量
捕捉最小/平均值和峰值以自动记录瞬变和变化
排除电阻测量的测试导线干扰的相对模式
可手动和自动选择量程，灵活性强
当导线插入错误的输入插孔时，输入警报会发出鸣叫声并闪烁 "Lead" 字样，以保护您的安全
易于使用
重要的附加功能可确保您在条件不佳的位置整天都能保持高工作效率。
即使您穿戴全套的 PPE，背光键盘按钮也可在照明不佳的区域为您提供良好的可视性
大型数字显示器和 2 级明亮的白色背光也增加了可视性
电池使用寿命长 - 无背光通常为 400 小时（碱性电池）
可选购的磁性挂钩，容易设置又方便读数，让您腾出双手做其它工作

Product overview: Fluke 28II Ex intrinsically safe true effective value digital multimeter
The DMM for fluke industry has all the measuring functions.
Whether you are inside or outside of ATEX zones 1, 2, 21, or 22, this tool provides you with all the testing and troubleshooting capabilities you need. There is no need to carry different instruments for different areas, and there is no need to worry about carrying non-explosion-proof grade tools through the explosion-proof required area.
4-1/2 digital mode for accurate measurement (20,000 words)
The true RMS ac voltage and current can accurately measure the nonlinear signal
Ac and dc voltages and currents up to 1000V and 10A can be measured (note that the Ex area requires reduced measurement)
Low pass filter ensures accurate measurement of voltage and frequency for variable speed drives (VSD)
Up to 200 kHz frequency and duty cycle can help you diagnose VSD and switch power supply
Resistance, connectivity and diode testing
The capacity range of a motor starting capacitor or component is 10,000 F
High resistance or leakage test conductance measurement
Capture minimum/maximum mean and peak values to automatically record transients and changes
A relative mode that excludes interference from a resistance measurement of a test wire
Manual and automatic range selection, flexibility
When the Lead is inserted into the wrong input jack, the input alarm will sound and flash the word "Lead" to protect your safety
Easy to use
Important additional features ensure that you remain productive throughout the day in a difficult location.
Even if you wear the full PPE, backlit keyboard buttons provide good visibility in poorly lit areas
Large digital displays and level 2 bright white backlights also add visibility
Long battery life - normally 400 hours without backlight (alkaline battery)
Optional magnetic hook, easy to set and convenient reading, let you free your hands to do other work
